To all it may concern.' Be it known that I. EDWARDD; Scm'u'rr,

a citizen of the United States, residingat Baltimore city, State of Maryland, have invented certain new and useful Improve ments in' lpparatus for Sterilizing and lass Vessels, of which the followlng is a specification. f

The invention relates to improvements in apparatus for sterilizing glass vessels, and.

for tempering the same, so as to prepare or vcondition them to withstand, without cracking: orA breaking, theexceedingly high temperature required in processing foodproducts.

In packing food-products in glass vessels, it is necessary or advisable, from a sanitary standpoint, to sterilize the-vessels, and also to temper thenr in order to eliminate thel danger of cracking or 4breaking during the act of" processing, hence the chief object of the invention is to provide an apparatus, whereby thev vesselsmay be subjected to zones of gradually increasing degrees of heat, 'the passage through the first heat-zone being amply suiicient toA .thoroughly sterilize the vessels, 'while the passage through the remaining'heatzones'will properly tem- A per or condition said vessels, so that they will withstand, as before stated, the excessive heatv incident to the processing or. cooking step.

To' thisV end theuin'vention consists-'chieiy in arranging within a suitable jacket or casing,a number of Specially constructed cha1n' bers vforming heating-zones; a suitable' carrier for conveying the vessels, to be treated,` -through the several chambers and zones, and

meansforlsupplying heat to the zones, the

heat? inthe successive zones beingl gradually .increased from'a moderateto a high heat,

s o that in' Vpassing through fthe first zone, the

vvessels will be subjected to a certain degreev 'of-heat, and -in passing through the remaining zones, they will bel subjected to graduallysincreasing degrees of heat, each succeeding zone being at a higher temperature than the-preceding-one, so that when the vessels 4have 'been 4subjected to the higher def v fgree-ofheat inthe last' zone, they will be. .vproperlytemp'eredi or conditioned to with- 'glsta'nd the excessive heat to which they will cracking or breaking,

'be subjected in the processing step, Without-p4 In the drawing: Figure 1 isa ytop lplan view ofthe apparatus, a'portion'of the caslng or jacket being broken away, 'showing the arrangement of the heat-supply-pipes relative to the .deiector-plat'es within` the u meral l indicates a suitable base or table supported upon intermediate legs 2,2 and end legs 3, 3'.. Suitably journaled in the respective end .legs are wheels4, around which is arrangedto travel an endless conveyerlbelt 5, adapted to support and convey the vessels lengthwise through -tlie apparatus.'

Mounted upon the 'table is a'casmg orjacket 6 which vextends approximately the entire length of the table, leaving at each end a short platform 7 from which may be handled thevessels. A heat-supply-pipe 8, preferably steam, is arranged on each side of the casing or jacket, the two pipes being connected together by a transverse pipe 11. The-end of one of the pipes Sis adapted to be connected '.with a suitable source of steam or other heat-supply, and a valve 9 is provided for turning on and` cutting oif the supply of heat.- The end of the'other pipe 8 is closed by a plug 10. Leading from each supply-pipe'S area number of jet supply-pipes 12, which, projecting through the sides of the casing,have their inner ends inclined toward ,the outer .or exitend of said casing. Each jetlpipe is provided with a needlei valve to control or regulate the inflow of heat, preferably steam."

'rality of chambers'by delector-plates 13,

which areA arranged adjacent to thejet-pipes,

and extend from the top to the bottom of the casing. Each deflector-plate is provided with la longitudinal extension 14, .against which the' heating-fluid from the jet-pipes is projected, and prevented from coming into immediate, vdirect contact .with the vessels.

ioo

l ,The outer or rear end of the casing is pro- .Y

. 25 nection with each inlet pipe,

-, same amount ofl steaiir, and that '1.0 ity, while `the others quicker and more intense l one-halt ot the distance at the Sametime, it

vided i a suitable stack 15, through which the heating-Huid, after passing through the various chambers,.is allowed to escape. v

It will ybe observed that the first two jets on cachiside ot the apparatus are of the same capacity or size, being,y adapted to admit the the followare ofthe same capac- 'toward the end of the thus providing a heat at the'icai portion ot the apparatus, than that which the jars must endure in ,traveling thelirst through the jacket. The arrangement of the detlectors within the jacket and the construction of the detiec'tors prevents the steam from coming into immediate direct contact with the jars, while ing two on each side jacket increase in size,

about a complete circulation and comparatively uniform 1 zone.

l refer to einplpy the valves 12 in conso that the heat supplied at any particular part of the jacket, may be regulated to a great nicety.

Suitably connected to the traine ot the apparatus is a drain trough 17 which extends the entire length ot the jacket and throughV which the. water of condensation -r passes lto the drain pipe 1G. It will be noted that this drain trough is inclined so that the water cannot' accumulatein the trough.
